John McEnroe annoyed fellow diners at Recipe, on the Upper West Side, Tuesday night by loudly recounting tales of his tennis glory days. The court legend entertained his wife and two friends with stories of “beating Bjorn Borg” and other victories. “He was several decibels louder than the average restaurant noise. It was obnoxious,” said a spy. The restaurant, which has fewer than 30 seats, confirmed that McEnroe was there but didn’t comment on his manners. McEnroe’s rep said, “Neither my client nor the manager on duty said that anyone complained about anything.”
